PSU Screw Configuration and Rotation Speed
Fenómeno do problema
[Problem Phenomenon] General-purpose screws processing PSU have heavy plasticization load and uneven melt; equipment alarms
Análise das causas
PSU suits a single-flighted full-thread constant-pitch low-compression-ratio screw with L/D ratio of 14-20; high viscosity requires the '2079851475616104452 machine to be equipped with a low-gear speed regulation device with stepless regulation at 15-45rpm to reduce screw load
Solução
Configure the screw with L/D 14-20 low compression ratio; control screw speed at 15-45rpm; when plasticization is insufficient, prioritize raising external heat rather than speed; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusão principal
PSU screws need low compression ratio L/D 14-20 paired with 15-45rpm low-speed plasticization; After confirming effectiveness, solidify the parameters and practices into the work instructions to prevent recurrence
